    Abstract: A filter has a filter cup, a filter element arranged in the filter cup, and a filter head. Filter cup and filter head are connected by a releasable bayonet-type connection with interacting locking parts connected to filter cup and filter head. A locking nose on the first locking part and a recess on the second locking part interact. The recess has an insertion/removal region for joining and separating locking nose and recess and also a locking region for hooking the locking nose. A spring between filter cup and filter head generates pretension on the locking nose in the recess. The recess has a locking shoulder with a shoulder tip between locking region and insertion/removal region. The locking nose has a locking tip. When locking tip and shoulder tip contact each other, the locking nose is forced by the spring into the locking region or into the insertion/removal region.

  • Patent number: 8673146
    Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

  • Patent number: 8613786
    Abstract: A fluid filter includes a base plate, a canister, and filtering media contained in the canister for filtering fluid from an inlet port to an outlet port. Notches are formed into an outer periphery of the base plate. An annular bead of the canister side wall is partially formed into the notches to provide a torque locking mechanism between the base plate and the canister. The terminating lip portion of the canister is wrapped around the outer face of the base plate and formed into an annular trough to directly secure the base plate to the canister. The annular trough includes a diverging outer wall that provides a narrow contact interface between the terminating lip portion and the retention corner of the base plate to thereby reduce moment loads induced therebetween as a result of high fluid pressures in the filter.
